Cut Bakken Core samples. Although often neglected, core samples always degrade to some degree in the process of cutting the core, handling it, and studying it. Non-destructive techniques are increasingly common, e.g., the use of MRI scanning to characterize grains, pore fluids, pore spaces and their interactions (constituting part of permeability) but such expensive subtlety is likely wasted ...
Ice core sample taken from drill. An ice core is a core sample that is typically removed from an ice sheet or a high mountain glacier.Since the ice forms from the incremental buildup of annual layers of snow, lower layers are older than upper ones, and an ice core contains ice formed over a range of years.
By withdrawing a small diameter core of rock from the orebody, geologists can analyze the core by chemical assay and conduct petrologic, structural, and mineralogical studies of the rock. It is also often used in the geotechnical engineering industry for foundation testing in conjunction with soil sampling methods.
The core sample has a diameter of about 2-1/2 inches (6.5 cm). "We did have quite a bit of difficulty starting our hole," said geologist and study co-author Andrew McCaig of the University of ...
A pollen core is a core sample of a medium containing a stratigraphic sequence of pollen. Analysis of the type and frequency of the pollen in each layer is used to study changes in climate or land use using regional vegetation as a proxy. [1] [2] This analysis is conceptually comparable to the study of ice cores.
Compressed sensing (also known as compressive sensing, compressive sampling, or sparse sampling) is a signal processing technique for efficiently acquiring and reconstructing a signal, by finding solutions to underdetermined linear systems.
Before and after photos of the deadly wildfires in the Los Angeles area have sent tens of thousands scrambling for safety and decimated neighborhoods.
Italian Sea Group is not liable in relation to the fatal sinking of Mike Lynch's superyacht, which killed the British tech billionaire and six others, its chief executive said on Tuesday. The ...
